ST:TNG skin if the channel actually has an APID. + +2004-10-17: Version 1.3.13 + +- Fixed checking for the presence of NPTL (thanks to Jouni Karvo). +- Making sure section filters are only set if the device actually has a lock + (thanks to Andreas Share for pointing this out). +- Fixed a possible NULL pointer assignment in cMenuText::SetText() (thanks to + Marco Schlüssler). +- Fixed a crash in case the last line in channels.conf is a group separator and + that group is selected in the channel display (thanks to Dick Streefland). +- Added cRingBufferLinear::Read() to read directly from a file handle into the + ring buffer. +- Using timeouts in ring buffers to avoid 'usleep()'. +- Clearing the 'Transfer Mode' ring buffer after clearing the device to avoid + an "almost full" ring buffer. +- Removed locking from cRingBufferLinear for better performance under high load. +- Using a cRingBufferLinear in cRemux to avoid unnecessary copying of data. +- Using a cRingBufferLinear in cTSBuffer and filling it in a separate thread + to avoid buffer overflows. Plugins using cTSBuffer will need to remove the + call to the now obsolete Read() function (see cDvbDevice::GetTSPacket() for + the new usage of cTSBuffer). +- cRemux::Process() has been split into Put(), Get() and Del() to allow for a + better decoupling of the remuxing and disk writing process. Plugins using + cRemux will need to be modified accordingly. +- The actual disk writing in recordings is now done in a separate thread to + improve the overall throughput. +- Changed cRemux so that it returns the maximum available amount of data with + each call, not just 2048 byte. +- Added a visual display of all cRingBufferLinear buffers for debugging. To + activate it, define DEBUGRINGBUFFERS in ringbuffer.h. +- Instead of cCondVar now using the new cCondWait (which also avoids a possible + "near miss" condition; thanks to Sascha Volkenandt for pointing out this one). + cCondVar is still present for plugins that use it (and VDR itself also still + uses it in cRemote). +- The cRingBuffer now does EnableGet()/EnablePut() only if the buffer is more than + one third full or empty, respectively. This dramatically improves recording + performance and reduces system load (thanks to Marco Schlüßler for doing some + testing regarding buffer performance and giving me some hints that finally lead + to finding out that this was the basic problem causing buffer overflows). +- Improved Transfer Mode (thanks to Marco Schlüßler for suggestions and testing). +- Fixed a possible crash with inconsistent SI data (thanks to Marcel Wiesweg). +- Fixed showing the replay mode if the OSD is currently in use (thanks to Kimmo + Tykkala for pointing out this problem). +- cOsdProvider::NewOsd() now always returns a valid pointer, even if the OSD is + currently in use (it will then return a dummy cOsd object and write a message to + the log file). +- Added Estonian language texts (thanks to Arthur Konovalov). +- Fixed 'newplugin' and libsi/Makefile to use the compiler defined in $(CXX) for + generating file dependencies (thanks to Andreas Brachold). +- Moved the initialization of aPid1 and aPid2 to the beginning of cDvbDevice::cDvbDevice() + to have them set in case a patch references them (thanks to Wayne Keer for pointing + this out). +- Completed the Russian OSD texts (thanks to Vyacheslav Dikonov). +- Avoiding unnecessary section filter start/stops (thanks to Marco Schlüßler). +- Made the "Channel not available!" message and mtInfo instead of mtError (suggested + by Wayne Keer). +- Made volume control more linear (thanks to Emil Naepflein and Udo Richter). +- Now skipping code table info in SI data (suggested by Milos Kapoun). +- Added missing Czech characters to fontosd-iso8859-2.c (thanks to Milos Kapoun). +- Fixed a crash in the time search mechanism (reported by Reinhard Nissl). +- If one PID can't be added, the whole cDevice::AttachReceiver() will now fail + and all PIDs added so far will be deleted (thanks to Marco Schlüßler for + pointing out this one). +- Now only saving channels.conf after a modification made by the user (avoids + lots of disk access due to automatic channel updates). Automatic channel + modifications will be saved every 10 minutes if no recording is currently + active. +- Removed the 'Log' parameter from the cChannel::Set... functions. Instead + checking if the channel has a non-zero number. +- Updated 'channels.conf.terr' for Hannover (thanks to Sven Kreiensen). -- cgit v1.2.3
